Eh

[This review was collected as part of a promotion.] I honestly don't feel any different. It's a bit of a bigger pill, which could be a problem for some people. It doesn't smell good, that's for sure. I don't know how I'm supposed to feel but I'm not noticing a difference unfortunately.

Feels natural

[This review was collected as part of a promotion.] I really am enjoying taking this supplement. I feel like my normal self when I take it, just a tad sharper and more focused. I don't get jittery like I do with caffeine, and there aren't any crashes like with sugar.

Alpha 🧠 on it

[This review was collected as part of a promotion.] I love this caffeine free supplement that helps promote mental clarity and flow state. It comes in a convenient little bottle that you could throw in a bag for travel and take to work or wherever with you. I haven’t noticed a huge difference but I did slightly notice that it helps support memory, focus, and cognitive processing speed. Unlike many other supplements, they don’t really have a taste. I think they’re worth purchasing.

Meh

[This review was collected as part of a promotion.] I received this product complimentary of Influenster for testing purposes in exchange for my honest opinion. Very easy to take. Little after taste. Thought it was ok but not great. For the value you only get a month supply. Packaging is child safe. Ingredients are easy to understand. If it’s something you’ve been wanting to try, I guess it’s ok to see if it’ll work for you

Focus supplement

[This review was collected as part of a promotion.] I’ve had a noticeable improvement in overall how I think and feel, with these, I feel more focused, my mind feels more clear, and overall, I feel more sharp. The price is fair and I think it’s worth it. It took a good few weeks for them to fully take effect, but they’re easy to take, and work well! The taste is impredecible and it has a good ingredients that don’t affect your body or your diet. The bottle is a good size to take on your purse.

No effect at all!

I heard about this product from Joe Rogan. I bought two bottles of this stuff. After going through them, I can say there was no change in memory or focus. This is nothing more than placebo pills. I'm embarrassed to have wasted so much money for nothing.

Good brain supplement

[This review was collected as part of a promotion.] I’m so happy to get this brain supplement to support my brain. It contains 30 capsules for 30 days. To me, this capsule is a little bit bigger than others, so considering to take a lot of water. It’s taste ok, not as much hard.

You have to understand your body

All people that say that they got sick is very understandable. When you take alpha brain, the compounds clean your body from all the bad things and the body immediately goes into safe mode so it shuts some things down, thats why you lose energy and get tired because the body needs that energy to clean your body, just like it happens when you get fever. Aha! So... what you should have done is just to continued to take them and I know for some people its not easy but thats just the way you have to do to get clean if you had some rough years...
